/package/generators element

The element /package/generators/generator specifies a tool or utility that is used to generate and/or configure software (source code, header files, configuration files, etc.) in the context of a project. For this purpose, a generator package description file (GPDSC) needs to be created (see <gpdsc>). The GPDSC file details the selected device, components, project files and conditions, as well as information about the generator and how it can be launched again for iterative development cycles. A GPDSC file follows the same schema as a static PACK. However, the files generated by the utility are not installed and managed centrally in the PACK folder, but locally within the project folder.

A generator can be associated with a component by it's name. Selecting the component will automatically include the files provided by the generator in the project. If the specified GPDSC file is not present, the generator command is executed by the environment to generate the files and GPDSC. In this way project specific configurations can be made, files being generated and included and maintained as part of the project.

# /package/generators

Grouping element for generators. Only one such group can exist in a PACK.

Parent | Chain
--- | ---
package | /package
Child Elements | Description | Type | Occurrence
generator | Description of the generator and the related files | GeneratorType | 1..*

The following variables can be used in the elements `<command>`, `<workingDir>`, `<argument>`, `<gpdsc>`:

Variable | Description
--- | ---
$P | PATH to current project
#P | PATH and name of the current project
$S | PATH to PACK folder containing the Device description used by the current project
$D | Name of the device configured in the current project

# /package/generators/generator

The generator section is used to provide the details about the tool that has been used to create the GPDSC file. At least one generator element must exist.

Parent | Chain
--- | ---
generators | /package/generators
Attributes | Description | Type | Use
id | Identifier of the generator tool. Can be used by other elements to determine the generator. | xs:string | required
Gvendor | Vendor name of the generator tool. | xs:string | optional
Gtool | Plain text name of the generator. | xs:string | optional
Gversion | Version of the generator tool. | xs:string | optional
Child Elements | Description | Type | Occurrence
description | Briefly describes the generator tool. | xs:string | 0..1
select | Complex type specifying the configured device. A device is uniquely identified by vendor, name or variant and processor name in case of devices with multiple processors. | GeneratorSelectType | 0..1
workingDir | Directory to be set as current directory before launching the `<command>`. This is either an absolute or relative path to PDSC or GPDSC file. If not specified, the current directory is the directory of the project configured by the environment. | xs:string | 0..1
command | Invocation command for the generator tool (for an example see top of the page). Command line options should be passed via `arguments`. | xs:string | 0..1
